Barbarian Natives can use a Totem . A foreigner barbarian does not gain the standard fast movement, uncanny dodge and improved uncanny dodge barbarian class features, instead he gains the following abilities.

Clerics are almost always foreigners, the Cloistered Cleric looks like a 1800 cleric, I would just add that lore is to reasearch only about foreigner's knowledge, and that they take only two domains(not three), and only if one of those domains is Knowledge they got the extended spell list.At first level clerics can't take any of the following domains: Plant,Nature,Fire,Water,Air or Earth.

Paladins get favored enemies as stated in Variant Paladin, also they get no spellcasting, but can take a a feat noted as a fighter bonus feat at 6th,10th,12th and 15th level of class.Paladins are always foreigners.

Native sorcerers get an animal companion instead of a familiar like this Sorcerer Variant.Sorcerers that grow up amongst foreigners don't get a familiar, instead they learn to cast spells while in light armor without the normal arcane spell failure chance.Also sorcerers are seen as devil's sons for both foreigners and natives, so they try to hide their powers most of the time.
